Shure BETA 87C

Popis produktu

Kondenzátorový zpěvový mikrofon, kardioidní charakteristika Excellent for touring professionals, the Beta 87C premium vocal microphone delivers studio-grade performance and a smooth, extended high-end frequency response in a cardioid condenser design. The microphone adds warmth to the frequency response and creates an ideal environment for in ear personal monitoring. And its highly consistent cardioid pattern offers excellent rear rejection. Vocalists who use earphone monitor systems such as Shure PSM® will appreciate how effectively the BETA 87C rejects ambient sound from the rear of the microphone. Smooth, wide frequency response, slight presence rise Uniform cardioid polar pattern for maximum isolation Minimum off-axis tone coloration Low-frequency roll-off compensates for proximity effect Three-stage pop filter minimizes breath pop and noise Break-resistant stand adapter Frequency response: 50 - 20,000 Hz Transducer Type Condenser (electret bias) Frequency Response 50 to 20,000 Hz Polar Pattern Cardioid Output Impedance Rated at 150 ohms (100 Ohms actual +/- 20%) Recommended minimum load impedance: 800 ohms Sensitivity (at 1,000 Hz) Open Circuit Voltage: -51 dBV/Pa (2 mV) (1 Pa = 94 dB SPL) Output Clipping Level 1000 Ohm Load at 1,000 Hz: -6 dBV (0.5 V) Maximum SPL 139 dB at 1,000 Hz (0.25% THD, 1000 Ohm load) Self-Noise 22 dB typical, A-weighted 24 dB typical, weighted per DIN 45 405 (equivalent sound pressure level; measured with true rms voltmeter) Dynamic Range 117 dB (maximum SPL to A-weighted noise level) Hum Sensitivity -5 dB equivalent SPL, maximum, in a 1 mOe field (60 Hz) Signal-to-Noise Ratio 72 dB at 94 dB SPL (IEC 651)*S/N ratio is difference between 94 dB SPL and equivalent SPL of self-noise A-weighted. Polarity Positive pressure on diaphragm produces positive voltage on pin 2 relative to pin 3 of the output connector. Power Phantom Supply Requirement: 11 to 52 Vdc, positive at both pins 2 and 3 Current Drain: 1.0 to 1.2 mA Connector Three-pin (XLR) professional audio Case Aluminum construction with painted blue metallic finish, and hardened steel grille with nickel satin chrome plating Dimensions See User Guide Net Weight Net: 207 grams (7.6 oz) Packaged: 565 grams (1.24 lbs) Environmental Conditions Operating: -18 degrees to 60 degrees C (0 degrees to 135 degrees F)(relative humidity 90%) Storage: -29 degrees to 74 degrees C (-20 degrees to 165 degrees F) (relative humidity 80%)
